Hi I just purchased 3- TK104 starter kits, one of the units was working fine but now when I send the command (check123456) responds: Power NO, battery 100%, GPS: No Signal, GPRS: ON, GSM: 19, the unit receives and sends commands, but it is not updating on Accutracking for the last 3 days, The unit is installed with the provided GPS Antenna and it has clear veiw of sky, the other 2 units are working fine. Please Help
Thanks Robert

As a troubleshooting step, you can always try to re-configure it with text messages.
Below are the text commands to full configure the tracker. You can send all of them one by one or just send a few till it gets working again. Every other commands except the “fix060s***n123456” command should reply back with a text message to you.

This unit works for about 1 day then the unit stops sending messages, when I type Check123456, unit replies that the GPRS is OFF, it turns off by itself, I type Reset123456 and unit starts working again, the other 2 units I have have been working fine since the first day I installed them, need help please
Thanks

Recently I purchased an 104 model. Everyhing works fine for example the sms command responds with the correct location as well as the gprs works fine. The only problem is that the blue light does not flash at all and when I send by sms the check command it says GPS : no gps. It is quite strange because every time I ask with an sms or through the gprs it responds with the location spot on.
